But consideration should be taken to cases in which one of the Contracting States takes advantage of the good faith of the other Contracting State of the Treaty, by making a future amendment of the law or by administrative practices that lead to significant losses of resources of the other Contracting State.
No obstante, deben tomarse en consideración los casos en que uno de los Estados contratantes aprovecha la buena fe del otro modificando posteriormente la ley o los procedimientos administrativos que dan lugar a pérdidas importantes de recursos del otro Estado contratante.
